Is it normal to be vomiting at 30 weeks of pregnancy?

yes its normal. I wasnt sick after the first month I was pregnant, but my mom was sick all through her pregnancy. some peoples body responds better to the pregnancy than others do. It helps to take flinstone vitamins instead of the prenatal, that's only because the prenatal gives you to much vitamin and can make you sick. so take two flinstone vitamins a day and that should make you less sick.
